NAD L 70 User Manual 2

With the introduction of the L 70 DVD/CD Surround Sound Receiver, NAD now offers the level of performance associated with its highly acclaimed full-size separates in an elegant, compact design. Designed to complement today's advanced video displays, its gleaming Titanium finish and elegant proportions make a sophisticated design statement. And unlike most other "all-in-one" systems, the NAD performs like an award winning NAD separate component. We have not made any performance compromises in our quest for convenience and style.

The Command Center for an Advanced Surround Sound System

By combining the DVD/CD player and digital surround sound receiver in one elegant package, one needs only to add the TV monitor and surround sound speaker package to the NAD L 70 to have theater quality sound in any room of the home. The L 70 is ideal for apartment and condominium dwellers, and makes for an outstanding bedroom or recreation room system. The supplied HTR-L70 Remote can operate your TV, VCR, satellite or cable tuner, and almost any other IR remote controlled device. The logical layout and illuminated keys make operating your AV system straightforward and enjoyable, and the HTR-L70, with it's ability to learn the remote commands of up to eight different devices, eliminates the clutter of multiple remote handsets. Unlike the "Home Theater in a Box" systems that include speakers (usually of questionable quality), the NAD L 70 allows complete freedom to choose speakers that fit your decor and suite your taste in sound.

Performance

The NAD engineers concentrated only on the truly important parts of a surround sound system. As the new surround sound formats allow for the same wide bandwidth and large dynamic range for the rear channels as for the front channels, all five channels are capable of putting out an equal and substantial amount of power. As usual with NAD, the L 70

uses discrete output stages only, including the surround channels. The benefits of this approach have been proven over the years in many acclaimed NAD amplifiers and receivers. Most products in this category are using digital IC amplifier modules, which allow for a very slim-line design, but cannot meet even the most basic hi-fi specs for noise and distortion. What's more, these amplifiers can only put out a very modest amount of power, far too little for a satisfying cinematic or musical performance. And to make matters even worse, these digital IC amplifiers used by our competitors cannot accurately drive real world speakers due to their poor tolerance of low impedance loads and almost total lack of dynamic power.

As one would expect from NAD, only high quality components have been used, such as high resolution ADCs (Analogue-to-Digital Converter) and DACs (Digital-to-Analogue Converter) from renowned manufacturer Cirrus Logic, to obtain the best possible performance.

Flexibility

Even though the L 70 DVD/CD Surround Sound Receiver may be far more compact than a separate DVD Player and Receiver of comparable performance, it still is very flexible. Three additional video sources (one front panel accessible - perfect for cameras and game consoles) and a 6 channel audio source can be connected (with the built-in tuner and DVD/CD player that potentially gives you access to six sources) of which two also offer S-Video inputs. Besides the Composite Monitor output, the L 70 also has an S-Video and Component/SCART RGB output as well. Two digital inputs (one optical, one coaxial) are provided, and, for easy transferring to a CD recorder or other digital recording device, the L 70 also sports an optical digital output. Rather than using spring clips for loudspeaker cable connection, as usually found on compact systems, the L 70 offers high quality loudspeaker binding posts, more associated with top-of-the-range full-size AV receivers. A preamp-level output for connection to a powered subwoofer is provided as well.

Advanced Features

The L 70 will automatically recognise DTS or Dolby Digital and will switch accordingly. Besides these modes, Stereo Enhanced (all channel stereo), ProLogic II, and EARS (an NAD exclusive) are available, all aimed at reproducing 2 channel stereo music in a realistic 5.1 surround mode, creating either a natural ambience, or an all out party sound. In all cases the sound is pure and undistorted, as opposed to those fuzzy "boingy" sound effects with lofty sounding names like "stadium" and "cathedral".

DVD and CD Features and Performance

Besides superb DVD picture qualiity, the NAD L 70 also offers a wide range of facilities such as Multi-Angle; Multi-Sound; Multi-Subtitle; Frame; Zoom and Repeat. All these facilities can be easily accessed with the supplied remote control. Through the extensive yet intuitive OnScreen-Display you can change the various settings and parameters for optimum performance.
